SILO-DOOR.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed February 4, 1916. Serial No. 76,214.

To all whom it may concern Be it known that I, CHARLES H. SHAVER, a citizen of the United States, and resident of the city of Bellingham, county of Whatcom, State of Washington, have invented certain new and useful Improvements in Silo-Doors, of which the following is a specification.

My invention relates to silos and consists of an improved form of door and mounting therefor.

The object of my invention is to provide a construction of door and its mountings which will permit of the door being swung inwardly and'out of the way.

In the drawings accompanying herewith 1 have shown my invention in its present preferred form of construction.

Figure l is a front elevation of a door in closed position and of the adjacent parts of the silo. Fig. 2 is a horizontal section showing the door in closed position in full lines and in partly open position by dotted lines. Fig. 3 is a like view showing the door in its fully open position.

The construction of the silo proper as herein shown, is the same as in the above case. In this silo the vertical ribs consisting each of two planks 1, placed with side faces in contact and secured in proper relationship by means of an inset strip or key 11, are connected by short horizontal boards 2, and when desired by outer lagging boards 20.

In silos of this character, it is customary to place a series of doors arranged above each other in one of the panels formed by two adjacent vertical beams 1. These beams are usually connected at the top and bottom of door opening by members 9 which serve as lintel and sill, respectively. In the construction shown, the vertical members 1, are provided with grooves 10 into which the edges of the door are seated.

The door is formed in two sections 3, which are connected along vertical edges by hinges 30. The door is supported and swung upon two arms 5, which are pivoted upon one of the vertical beams 1 at the side of the door opening. The eyes 6 in which the arms 3 are pivoted, are located close to the outer face of the door. The arms 5 are preferably made of round bar iron, bent at one end to form a pivot 51, which enters the eye 6. The swinging ends of arms 5 are formed into eyes 50 for the reception of a pivot bolt il.

The swinging and carrying arms 5 are not pivoted directly upon the door, but upon an intermediate member which is in turn pivoted upon the door. This intermediate member consists of a bar having its central portion 4 of a length to extend between the arms 5 and portions 40 at the ends of central section 4:, which are bent laterally and with their tips 42 bent into substantial parallelism with the central portion 4. The tips 42 form the pintle of the hinges 30 which connect the two halves of the door.

The door carrying and swinging arms 5, are of such length between their pivot points that their outer pivots 50 extend beyond the position occupied by the pivot of hinges 80, whereby the lateral portions 40 of the illtermediate members extend backward or toward the main pivot of the arms 5.

In opening the door the center or pivoted edges of the door are pushed inward. This may be somewhat assisted by pulling outward and laterally upon the intermediate member 4. The parts will then assume the position shown by dotted lines in Fig. 2, which will permit them to clear the flanges 12 at the inner side of the channel 10. The parts of the door are then swung around to one side into the position shown in Fig. 3.

Having thus described my invention, what I claim as new, and desire to secure by LettersPatent of the United States of Amerlca, 1s:

1. A silo door divided into two leaves hinged together along their meeting edges, a hinged door swinging member pivoted at one side of the door opening and extending heyondthe line of division between the parts of the door, a member forming the pintle of the hinges which connects the two leaves of the door and having a pivotal connection with the swinging end of said door swinging member located laterally of the axis of (0111c hinges which connect the leaves of the oor.

2. A swinging support for a silo door comprising a pair of arms hinged at one side of the door opening, and a pivoted link connection between the swinging ends of said arms and the central part of the door, said arms being of a length that the connecting links extend from the ends of said arms backward toward their pivots when the door is in closed position.

3. A swinging support for a silo door comprising two arms pivotally supported by one end at the side of the door opening, an lntermediate member connecting the swinging ends of said arms with the door and comprising a bar having its ends extending latera'lly from its central part and then terminating in tips which are essentially parallel with said central part, said terminal tips being pivoted upon the door-and the by one end'at thesideof the door opening,

an intermediate member connecting the swinging ends of said arms with the'door and comprising a bar having itsends extending laterally from its central part and then terminating in tips which are essentially parallel with said central part, said terminal tips being pivoted on the door and the swinging arms being pivoted to'the lateral parts ofthe'intermediate' member, the

i v i ing arms being ofa length to carry their'points of pivotal connection with the intermediate member beyond the pivotal fconne'ction of said intermediate member sition. H

with the door when the door is in closed po- In a'clo-sure for silos, in'combination, a

door-casing having twoopposite groovedror channeled jambs, a door divided into two parts upon a line paralleling said channeled jambs, hinges connecting said door parts, door swinging and carrying arms pivoted by one end upon one of said channeled jambs and of a length to extend beyond the axis of the hinge connection between the.door

parts, and an intermediate member connecting the swinging ends of said door carrying arms with the door adjacent said hinge axis.

6. In a closure for silos, in combination, a door casing having two opposite grooved or channeled jambs, a door divided into two parts upon a line'paralleling said channeled jambs, hinges connecting said door parts, door swinging and carrying arms pivoted 'by one end upon one of said channeled jambs, an intermediate member pivotally connecting the swinging ends of said arms with the door adjacent the axis of the hinges which connect its parts, the combined length of said door swinging arms and intermediate connection being greater than the separation of the supporting pivot'of said arms from the connection of said intermediate member with the door when the door is in closed position.

Signed at Seattle, WVashington, this 12th day of January, 1916.
